What this op amp brings to a single-supply signal chain
Input offset voltage is 1 mV typical, input bias current 150 nA.
The LT1797 runs from 2.7 V minimum to 12 V maximum. At 1.4 mA supply current, it is not an ultra-low-power part, but the current budget is reasonable for a multi-channel board where each op amp draws similar quiescent current.
Output drive and package — what fits the board
Each channel can source or sink 50 mA, enough to drive a modest headphone load or a small relay coil through a transistor. The TSOT-23-5 footprint is about 2.9 mm × 1.6 mm, which saves board area compared to an SOIC-8. The tape-and-reel suffix (#TRMPBF) means it ships on 7-inch reels, typical for automated pick-and-place. The package is ROHS3 compliant.
